The fast evolution of Information and Communication Technology (ICT) introduced a new generation of learners that have been adopted mobile devices and Web 2.0 technologies to get information and ...communicate. The Web 2.0-based tools, such as blogs, wikis, Facebook, Instagram, etc, offer huge possibilities for collaboration. In this way, the main purpose of this research was plan an activity on wiki platform for Reinforced Concrete discipline in Civil Engineering course and answer the questions: (1) How should collaboration be effectively measured on wiki platform? (2) What is the students' point of view about using wiki platform for a collaboration activity? Wikispaces Classroom platform was chosen for the project because it is a free social writing platform, suitable for collaborative learning. Furthermore it works on modern browsers, tablets, and smart phone. A total of 167 students of Civil Engineering course were monitored on Wikispaces® platform. All students’ actions were analyzed and classified as low, medium or high level of collaboration. At the end of the project 111 students answered a questionnaire and 10 students participated of an informal interview where they expressed their opinion about the platform, the activities and the relationship with online peers. A descriptive statistical analysis of the data collected from the platform and the questionnaires answered by the students was performed. The results indicated that wiki platform is an important way to develop innovative activities and tasks for the purpose of to improve skills of engineering students such as: writing communication, organization, collaboration and critical thinking.
Increasing concern over microplastics has recently brought increased attention to studies on microplastic toxicity. Here, we conduct a systematic review on toxicity of microplastics that focuses on ...identifying data gaps in the mechanisms of microplastic toxicity. We observe that microplastic toxicology research thus far has focused on ecotoxicity using apical endpoints and only a few studies deal with toxicity mechanisms. Based on this review, we propose putative Adverse Outcome Pathways (AOPs) applicable to microplastic management to understand microplastic toxicity. We matched toxicity mechanisms and apical endpoints to a key event (KE) and adverse outcome (AO) information from the AOP Wiki. Overall, our results suggest that the molecular initiating event (MIE) was reactive oxygen species (ROS) formation and the AO was increased mortality, decreased growth and feeding, and reproduction failure. However, there are a limited number of studies on toxicity mechanisms of microplastics and, therefore, evidence concerning the relationship between KEs is not sufficient. Clearly, more studies on toxicity mechanisms are required to fill these gaps in data. This study also suggests that the AOP framework is a suitable tool to integrate existing data from various literature sources and can identify data gaps in microplastic toxicity mechanisms.

Das beschriebene Projekt verfolgt eine detaillierte Kartierung der Services und technischer Infrastrukturen aller DFG-geförderten Fachinformationsdienste. Dadurch soll die Bildung von Kooperationen ...unterstützt werden sowie die Erhöhung der Nachnutzbarkeit und Interoperabilität der Angebote und Entwicklungen. Die Umsetzung knüpft an das öffentliche webis-Wiki an, das an der SUB Hamburg betrieben wird und die derzeit einzige übergreifende Informationsstruktur der Fachinformationsdienste ist. Es wurde um ein FID-Community-Wiki erweitert, das dem wechselseitigen Austausch von Erfahrungen und Informationen der Fachinformationsdienste dient. Der Aufbau und die gewonnenen Erkenntnisse des Projektes werden hier skizziert.
İngilizce öğretmek için hevesli olan öğretmenleri yetiştiren eğitmenler olarak, öğrencilerimizin genel olarak şiir öğretme fikrinden korktuğunu görüyoruz. Ayrıca, şiirin onların gönderildikleri ...okullarda kendi alanlarında öğretmeleri istenen en yaygın tür olduğunu da görüyoruz. Kanada ve İngiltere'deki mesleğe yeni başlayan öğretmenleri bir Wiki'de bir araya getiren bu projeye onların şiir öğretme konusunda hissettikleri bazı gerilimleri araştırmak için giriştik. Projeye dahil olan 56 öğretmen adayı tarafından ifade edilen yedi önyargı belirledik: Öğrenciler şiiri sıkıcı bulmakta ve ona direnç göstermekteydiler; okul hayatları boyunca öğretmen adaylarının tecrübe ettiği şekliyle şiir seçkinci ve çoğu zaman erişilemezdi; şiir çoğu sınıfta yüzeysel olarak vardır ve zaman kısıtlamaları söz konusu olduğunda İngilizce programlarından kolayca çıkartılabilen bir süs olarak kabul edilir; öğrenciler tarafından yazılan şiiri değerlendirmek zordur; analize aşırı vurgu yapmak şiir öğretiminin çoğu zaman merkezinde yer alır; ve şiir tek başına yapılan bir sanattır. Bu makalenin geri kalanında bu ön yargıların etrafındaki bazı yorumları ve öğretmen adaylarının sözlerinin kendilerinin yaptığı öğretim ve genel olarak şiir öğretimi üzerindeki olası etkilerini ele alacağız.
Abstract
The adverse outcome pathway (AOP) framework provides a practical means for organizing scientific knowledge that can be used to infer cause-effect relationships between stressor events and ...toxicity outcomes in intact organisms. It has reached wide acceptance as a tool to aid chemical safety assessment and regulatory toxicology by supporting a systematic way of predicting adverse health outcomes based on accumulated mechanistic knowledge. A major challenge for broader application of the AOP concept in regulatory toxicology, however, has been developing robust AOPs to a level where they are peer reviewed and accepted. This is because the amount of work required to substantiate the modular units of a complete AOP is considerable, to the point where it can take years from start to finish. To help alleviate this bottleneck, we propose a more pragmatic approach to AOP development whereby the focus becomes on smaller blocks. First, we argue that the key event relationship (KER) should be formally recognized as the core building block of knowledge assembly within the AOP knowledge base (AOP-KB), albeit framing them within full AOPs to ensure regulatory utility. Second, we argue that KERs should be developed using systematic review approaches, but only in cases where the underlying concept does not build on what is considered canonical knowledge. In cases where knowledge is considered canonical, rigorous systematic review approaches should not be required. It is our hope that these approaches will contribute to increasing the pace at which the AOP-KB is populated with AOPs with utility for chemical safety assessors and regulators.

An emphasis of the book lies in the design and prototypical implementation of ...tools for the integration of ITSM-relevant information into the semantic wiki, as well as tools for interactions between the wiki and external programs. The result of the book is a platform for agile, semantic wiki-based ITSM for IT administration teams of SMEs.
Concerning the effectiveness of using wikis for project-based learning in higher education, this study compared the perceptions and actions among students in three undergraduate courses of different ...disciplines, English Language Studies, Information Management, and Mechanical Engineering, who used wikis in their course assignments. Using a triangulation methodology, the study shows that students mostly hold positive attitudes towards the use of wikis for project-based learning. However, significant differences exist in 5 aspects, such as “Motivation” and “Knowledge Management”, in the questionnaire among all participants. Additionally, the level of participation and core actions on the wikis vary among students of the three disciplines. These findings can be explained by the variations in participants' previous learning experiences, their technical backgrounds and the relationship between learning goals and collaborative learning. A series of insights are offered in the context of the use of wikis in project-based learning in higher education.
•Instructional support for students’ collaborative project-based learning with wikis is critically needed.•Disciplinary difference is one of the key factors in affecting students’ perceptions and actions with wikis in project-based learning.•Some useful suggestions are put forward for teachers’ adopting wikis in project-based learning.
The De Jonge Wiki is a digital, scientific research database on the building history of Arenberg Castle in Heverlee, Belgium. As a prototype it is intended to show how information on complex ...structures can be presented according to today’s state of the art. The aim is to work according to international quality standards as well as making the information easily accessible to users. For this purpose, both MediaWiki and Wikibase were used as software. In this way, a user interface was created that is visually and functionally reminiscent of Wikipedia and can therefore be intuitively understood by users without prior knowledge while the corresponding semantic data is stored in a database in the background.
In recent years, we have witnessed the rapid proliferation and widespread adoption of a new class of information technologies, commonly known as social media. Researchers often rely on social network ...analysis (SNA) when attempting to understand these technologies, often without considering how the novel capabilities of social media platforms might affect the underlying theories of SNA, which were developed primarily through studies of offline social networks. This article outlines several key differences between traditional offline social networks and online social media networks by juxtaposing an established typology of social network research with a well-regarded definition of social media platforms that articulates four key features. The results show that at four major points of intersection, social media has considerable theoretical implications for SNA. In exploring these points of intersection, this study outlines a series of theoretically distinct research questions for SNA in social media contexts. These points of intersection offer considerable opportunities for researchers to investigate the theoretical implications introduced by social media and lay the groundwork for a robust social media agenda potentially spanning multiple disciplines.
